ROOFING MATERIAL.

I Application filed December 21, 1921. Serial No. 523,838.

To all whom, it may concern:

Be it known that .I, N(')Rl\fAN l. HARSH- nnnoru, :1 ch izen of the United States, residing at (hit-ago. in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Roofing Materials, of which the following is a specification.

This invention relates to roofing. material, and it has for its object the production of suitable shingles or strips of sl'iingling material for covering root's effectively and so as to give a pleasing appearance.

(It the accompanying drawings'Fig. l is a perspective view of strips of shingles laid horizontally on a roof,- and which embody the features of my invention; Fig. 2 is an enlarged cross-section along the line 2-2 of Fig. 1; Fig. 3 is a view of the lower side of :Fportion of one ofthe strips; and Fig. 4 is a diminished plan view of the strips arranged to extend up and downs. slanting roof.

Any suitable material may be used for making thestrips of root covering which embody the features of my invention. I prefer for the purpose ordinary sheets of felt, asphalt and slate. Any suitable length or width of strips may be used in carrying out the invention. In covering a roof with ordinary strips of roofing material, if the' strips are laid flatly on the roof. overlapping each other more or less, there is a tendency for the strips to bow up or buckle and curl in places. and the appearance of the roof is not-pleasing; also the roof is not so well protected where joints are formed. To better protect the roof andimprove the appear-' ance, and for other reasons, I provide strips 5 and form transverse folds 6 in the strips,

'which improve the appearance of the roof and materially assist in preventing buckling and curling tendencies.

The strips may be laid horizontally, as indicated in Fig. 1, or transversely, that i", running down the root from the peak to the eaves. And the loops may be three-ply as indicated, or may have more folds, if desired.

lVherc the strips are not of suflicient length to reach from one end of the roof to the other, or from the peak to the eaves, the ends of two strips may be connected in any suitable manner. I prefer for the purpose to make the connection in one of the folds 6 by having the two ends ahut and thus-form the center portion 7 of the fold; and I provide an otisetportion 8 on each folded strip 'end, the arrangement being such that the shoulders 9 of the ofi'set portions abut when the two ends are in place. By this arrangement relative longitudinal movement of the strips in one direction is prevented by the abutting ends of the strips and relative transverse movementin one direction is prevented by the abutting shoulders 9; hence, when the strip having the lower end is laid in place, the upper end of the continuation strip is very quickly placed. By this .method of joining the ends there is no opportunity for water to leak through as the two ends not only are lapped, but the lower end is turned upwardly and inwardly and, hence, prevents water from working inwardly beyond the end.

Each strip may be lapped onto the lower adjacent strip, as much as may be desired. I- prefer to lap them about half way,'as is indicated. And in case of the transverse strips running from the peak to the eaves, 80. one strip may lap on both edges of the ad Jacent strips.

In order to give the folds more stren h, or a more pleasing appearance, I provi ea filler 12 of some suitable material. These fillers are placed in one of the 100 s of the folds 6. extending transversely of t e strips. These fillers not only increase the thickness ofthe fold so as to give it a more definite appearance on a roof, butthey also stiffen the strips along the folds and thereby pr vent the irregular tendencies such as buckling, or Warping, or the like. The fillers may be inserted in any suitable-manner; I I prefer to insert them when the roofing strips. are formed, and to have them held securely in place in any suitable manner, as' by the adhesive material 13.

As stated, the strips -may be laid longitudinally or transversely of the roof as may 1 be desired. In Fig. 4 I have indicated the strips running transversely; and the positioning of the folds in the same strip or in adjacent strips may be as desired. I prefer to lay the strips so that the folds of one strip are staggered with relation to theiolds 0f the adjacent strips. But, while I have illus trated the left-hand edge of the fold 6 in the upper strip abuttingagainst the righthand edge of the fold in the lower strip, yet no it is to be understood that these upper and lower folds may be separated as much as may be desired,

' folds therein, one of the strips being aligned Withand being a continuation of the other strip, the adjacent ends of the said two stripsabutting together and forming the central portion of a 'fold, each of said adjacent ends having an offset portion'with a shoulder'thereon, the shoulders of the offset portions abutting together, thereby preventing relative transverse movement in one direction of said two ends.

2. An articleof manufacture comprising a strip of roofing material having a plurality of transverse folds, and having one end folded to form a fractional portion of one loop of a transverse fold, the said end of the strip having an offset portion betwee the side edges of the strip. a

3. An article of manufacture comprising a strip of roofing material having one end folded to form a fractional portion of one loop of a transverse fold, and the other end of the strip being similarly folded but on the side of the strip opposite to the fold on the first mentioned end, each of the edges of the ends comprising two straight portions, not in the same line but parallel with each other.

4. An article of manufacture comprising a strip of roofing material having a plurality of transverse folds spaced from its ends and having one end folded to form a fractional portion of one of the sides of a transverse fold, and a filler of material running transversely of said strip of roofing material and positioned in each of said folds and in said fractional portion thereof.

5. An article of manufacture comprising a strip-of roofing material having a plurality of transverse folds spaced from its ends and having each end folded to form a fractional portion of one of the sides of a transverse fold,,and a filler of material run ning transversel of said strip'of roofing material and positioned in each of said folds spaced from the end and in one of said fractional portions of a loop, and having the facing surfaces of the sides of the fold of the thcr end of the strip in contact with 'each thenln testimony whereof, hand.
